Question

Guys please help tomorrow is my exam,, describe briefly and no google answers because I have already checked there..

Describe how the scattering of α-particles by thin metal foils provides evidence for the nuclear atom.

I will sure mark you the brainliest..

Answer 1

majority of particles passed through atom without deflection this showed that there are a lot of empty spaces in atom.
a few particles got deflected at small angles this showed that there is a positive charge inside atom
very few particles which passed through centre deflected back 180 degrees. this showed that positive charged nucleus is concentrated in the centre.

hope this helps mark as brainliest

Answer 2

$\huge\blue{\boxed{\boxed{\mathcal{\bf\purple{♡}{\pink{Answer}\purple{♡}}}}}}$

A beam of a-particles was passed through the foil and some of the alpha particles (are positive) came out from different directions/ repelled. This meant that the positive charge in atoms was highly concentrated at one point for it to scatter the alpha particles. This shows that the atom had a positive nucleus with electrons outside the nucleus.
